MIG is only an auto class generator that makes methods for any struct that
contains the payload, so you can work with methods rather than accessing
and converting the bytes. Nothing else. To communicate through
serialforwarder (TCP-IP) or directly through the serial port is transparent
at this point.
I have not used for many months...
Be sure to get familiar with the tutorials checking that you are able to
transmit and receive data from the PC to the mote, writing directly in the
serial port and through serialforwarder.
What I suggest is 1) to send any packet to the mote, 2) blink a led
indicating that the mote got something, i.e. whenever the serial active
message has been received, and 3) printf whatever it has understood.
What I did to transmit to the mote was:
import net.tinyos.message.*;
public class TinyOS2mote implements MessageListener {
private MoteIF moteIF;
// Register channels listened in the PC coming from the mote, in the
constructor of your class
this.moteIF.registerListener(new TinyOSControlANSMsg(), this);
this.moteIF.registerListener(new TinyOSLogMsg(), this);
this.moteIF.registerListener(new TinyOSOutputResultMsg(), this);
this.moteIF.registerListener(new TinyOSParametersMsg(), this);
this.moteIF.registerListener(new TinyOSCalibrationMsg(), this);
public void messageReceived(int to, net.tinyos.message.Message message) {
String str;
int value;
int amType = message.amType();
switch (amType) {
....
}
public void sendOrder(){
TinyOSControlCMDMsg msg = new TinyOSControlCMDMsg();
try{
msg.set_instruction ( (short) instruction );
msg.set_nodeId ( (short) nodeId );
moteIF.send(MoteIF.TOS_BCAST_ADDR, msg);
System.out.print("Sending COMMAND to serial port\n");
} catch(Exception ioexc) {
...
}
}
Then, when you launch the java class point to the serialforwarder:
java TinyOSconsole -comm sf@localhost:9002
That is it. I am not sure whether this is what you are looking for...
Cheers!
